PublicationThe Rise of Crowd Aggregators - How Individual Workers Restructure Their Own Crowd( 2017-02-12)
;Durward, DavidCrowd work has emerged as a new form of digital gainful employment whose nature is still a black box. In this paper, we focus on the crowd workers – a perspective that has been largely neglected by research. We report results from crowd worker interviews on two different platforms. Our findings illustrate that crowd aggregators as new players restructure the nature of crowd work sustainably with different effects on the behavior as well as the existing relationships of crowd workers. We contribute to prior research by developing a theoretical framework based on value chain and work aggregation theories which are applicable in this new form of digital labor. For practice, our results provide initial insights that need to be taken into account as part of the ongoing discussion on fair and decent conditions in crowd work.Type: conference paper -
PublicationIs There PAPA in Crowd Work? : A Literature Review on Ethical Dimensions in CrowdsourcingThe phenomenon of crowdsourcing has emerged as a new pattern of digitally mediated collaboration. This novel socio-technical arrangement changes the organization of work as well as its general nature and takes place in information systems (IS) in which humans face many threats to their dignity. For this reason, the importance of ethical issues within this new form of employment arises. Hence, in this paper we focus on the ethical issues in crowd work – a perspective that has been largely neglected by current crowdsourcing research. We analyze recent crowdsourcing literature and extract ethical issues by following the PAPA (privacy, accuracy, property and accessibility of information) concept, a well-established approach in IS. The review focuses on the individual perspective of crowdworkers, which addresses their working conditions and benefits. Although, the literature review exhibits that there are PAPA dimensions in crowdsourcing, only few focus on the crowdworkers as individuals. Our findings contribute to further research in crowdsourcing by introducing an ethical framework and give practical insight into how to design sustainable and ethical crowd work.Type: conference paper

PublicationWhen is Crowdsourcing Advantageous? The Case of Crowdsourced Software Testing(Boğaziçi University, 2016)
;Knop, Nicolas ;Müller-Bloch, ChristophCrowdsourcing describes a novel mode of value creation in which organizations broadcast tasks that have been previously performed in-house to a large magnitude of Internet users that perform these tasks. Although the concept has gained maturity and has proven to be an alternative way of problem-solving, an organizational cost-benefit perspective has largely been neglected by existing research. More specifically, it remains unclear when crowdsourcing is advantageous in comparison to alternative governance structures such as in-house production. Drawing on crowdsourcing literature and transaction action cost theory, we present two case studies from the domain of crowdsourced software testing. We systematically analyze two organizations that applied crowdtesting to test a mobile application. As both organizations tested the application via crowdtesting and their traditional in-house testing, we are able to relate the effectiveness of crowdtesting and the associated costs to the effectiveness and costs of in-house testing. We find that crowdtesting is comparable in terms of testing quality and costs, but provides large advantages in terms of speed, heterogeneity of testers and user feedback as added value. We contribute to the crowdsourcing literature by providing first empirical evidence about the instances in which crowdsourcing is an advantageous way of problem solving.Type: conference paper -
